ESP32 Edge AI People Counter Kit with ESP32 + Camera
ESP32-S3 Edge AI People Counter Kit: Build a Real-Time Footfall Tracker with On-Device AI
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced kit transforms an ESP32-S3 and OV2640 camera into a self-contained people-counting system. A custom FOMO object detection model runs entirely on-device, detecting when a person crosses a virtual line in real time. Hourly counts are pushed to the cloud — perfect for footfall analytics at retail entrances, event gates, or campus labs.
What You'll Build
A compact, battery-friendly edge AI module that mounts over any doorway. The camera streams video to the ESP32-S3, which runs an optimized FOMO model to count people crossing a user-defined line. Count and timestamp are shown on an OLED, logged to a microSD card, and published to a cloud dashboard every hour via WiFi.
What You'll Learn
- Train a FOMO object detection model using Edge Impulse with your own line-crossing dataset
- Deploy a quantized INT8 model on ESP32-S3 and interpret bounding box outputs in real time
- Implement a directional line-crossing algorithm using centroid tracking
- Set up a MQTT/HTTP cloud pipeline to post hourly aggregated counts

Who This Kit Is For
Ideal for B.Tech ECE/EEE students building final-year projects, Smart India Hackathon participants prototyping footfall analytics, and engineering enthusiasts from IITs, NITs, and VIT seeking hands-on edge AI experience. The project aligns with CBSE Class 12 AI curricula and ATL advanced tracks, giving you a tangible, cloud-connected IoT solution to showcase.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion provides real-time debugging tips and wiring checks, and our WhatsApp support team responds within business hours.
How do I train the FOMO model for my own entrance?
We provide a pretrained model and sample dataset, but you can retrain it using Edge Impulse — we include a custom data collection firmware that captures images with a phone camera for easy labelling.
Can I change the counting line and threshold?
Yes, the line position and sensitivity are adjustable via a simple config file on the microSD card. No recompilation needed.
Which cloud platforms are supported out of the box?
The kit ships with ThingSpeak integration; you can swap to Blynk, Arduino Cloud, or a custom MQTT broker using the modular code structure.
OV2640 + ESP32-S3 FOMO model counts people crossing a line in real time. Posts hourly count to cloud.
